Labeling the Principal Lobes of the Cerebrum

The cerebrum, the largest part of the brain, is divided into distinct lobes that each serve specific functions. Let's dive into their locations and get familiar with this fascinating part of our nervous system!

The Four Main Lobes

1. Frontal Lobe

• Located at the front of the brain (think "forehead area")
• Extends from the anterior (front) of the brain to the central sulcus
• Takes up about one-third of the cerebral hemisphere

Think of the frontal lobe as being right behind your forehead - it's the most "forward" part of your brain!

2. Parietal Lobe

• Positioned behind the frontal lobe
• Extends from the central sulcus to the parieto-occipital sulcus
• Located at the top and sides of the head

3. Temporal Lobe

• Found on the sides of the brain
• Located roughly where your ears are
• Separated from the frontal and parietal lobes by the lateral sulcus (also called the Sylvian fissure)

4. Occipital Lobe

• Situated at the back of the brain
• The smallest of the four main lobes
• Located at the rear of the parietal and temporal lobes

5. Limbic Lobe

Each lobe is present in both hemispheres of the brain, meaning you have a left and right version of each lobe!

Students often confuse the central sulcus with the longitudinal fissure (which separates the left and right hemispheres). Remember, the central sulcus runs vertically on each hemisphere!

When learning the locations, it helps to use your own head as a reference. Touch your forehead (frontal), the top of your head (parietal), the sides near your ears (temporal), and the back of your head (occipital) to better understand their positions.
